I don't understand the difference between DOMNodeRemovedFromDocument and
DOMNodeRemoved. Can someone explain?

DOMNodeRemoved
    Fired when a node is being removed from its parent node. This event is
dispatched before the node is removed from the tree. The target of this event is
the node being removed.

        * Bubbles: Yes
        * Cancelable: No
        * Context Info: relatedNode holds the parent node

DOMNodeRemovedFromDocument
    Fired when a node is being removed from a document, either through direct
removal of the Node or removal of a subtree in which it is contained. This event
is dispatched before the removal takes place. The target of this event is the
Node being removed. If the Node is being directly removed the DOMNodeRemoved
event will fire before the DOMNodeRemovedFromDocument event.

        * Bubbles: No
        * Cancelable: No
        * Context Info: None

I think I might implement this (I'm hacking nsDocument for mutation events
anyway for for bug 201236), but I will not attempt to follow bug 231676.

The testcase given is not comprehensive enough.  DOMNodeRemovedFromDocument
fires once for every node removed, directly or indirectly.  If you remove the
bar element from:

<foo><bar><one/><two/></bar></foo>

Then you must fire:

(no specific order to the first three)
DOMNodeRemovedFromDocument @ one
DOMNodeRemovedFromDocument @ two
DOMNodeRemovedFromDocument @ bar
NodeRemoved @ bar

and then remove the bar element.

Marking as dup of bug 74219, which will require nearly identical work to implement.
